Traffic policies overview
This chapter describes how traffic policies are implemented and configured in the PowerConnect
devices.
Dell devices use traffic policies for the following:
•
•
Traffic policies consist of policy names and policy definitions:
•
•
When you apply a traffic policy to an interface, you do so by adding a reference to the traffic policy
in an ACL entry, instead of applying the individual traffic policy to the interface. The traffic policy
becomes an active traffic policy or active TPD when you bind its associated ACL to an interface.

Traffic policy name – A string of up to eight alphanumeric characters that identifies individual
traffic policy definitions.
Traffic policy definition (TPD) – The command filter associated with a traffic policy name. A
TPD can define any one of the following:
•
Rate limiting policy
•
ACL counting policy
•
Combined rate limiting and ACL counting policy
The maximum number of supported active TPDs is a system-wide parameter and depends on
the device you are configuring. The total number of active TPDs cannot exceed the system
maximum. Refer to
"Maximum number of traffic policies supported on a device"
